I sure as hell hope not - remember how crappy your average movie to game game has been in the past? Now imagine most all titles being that bad.
Yup, I have similar concerns. It would be OK if the movie corps would allow them creative independence, but I'm skeptical that they would be able to help themselves from interfering and screwing up the games. That industry is just too full of head-up-their-ass type personalities IMO. Some movie corps might able to pull it off, but when even LucasArts -a company with a previous good game publishing record- can't seem to get it right you really have to wonder.
